DigitalGlobe EarthWatch – Download Directly From the Entire DG Archive Now!!

Do you have the need for regularly updated images of locations around the world?

Perhaps you need imagery to integrate with an OEM solution you are developing?

Or maybe your organization uses large amounts of high-resolution imagery each year, and you are seeking a low-cost option for this data?

If you answered yes to any or all of these questions, then the solution you are looking for is DigitalGlobe’s EarthWatch (formerly called Global Basemap or GBM).

With EarthWatch, you have access to millions of square kilometers of streamed imagery with low cloud-cover and off-nadir angles. This data is accessible in web-mapping services and in an online viewer. Perhaps the most important feature of EarthWatch are the regular streaming updates you can receive as out-dated imagery is often of little or no use to our valued clients.

And if the EarthWatch streaming database lacks the coverage you need, Premium users are now able to download any image from the entire DigitalGlobe archive (minus IKONOS data) in a wide variety of formats!

April 2019 Product Update

The available DigitalGlobe EarthWatch imagery over China and Russia by location and with the most recent coverage date indicated with varying colors. In the vast majority of locations, there are multiple imagery dates available.

Without question the biggest news we have this month is the addition of direct data downloads (Premium users only) from the entire DigitalGlobe imagery archive (minus IKONOS)! This is an exciting change, particularly for clients looking for orders well below the typical minimum of 25 square kilometers for offline GeoTIFF deliveries. Send us an email at sales@apollomapping.com if you would like to find out more about this exciting new offering!

As for our normal monthly updates, in March we checked out the EarthWatch coverage in Europe, and for April we move to the east with a look at the same coverage over China and Russia.
